IMPROVEMENT IN SOCKETS FOR TOOL-HANDLES.

Specification forming part of Letters Patent N o.A 180,126; dated July25, 1876; application filed y June 9, 1876.

To all whom it may concern:

Be it known that I, CHARLES ATWooD HARDY, of Philadelphia, in the Stateof Pennsylvania, have invented an Improvement in Sockets for`Tool-Handles, of which the following is a specilicationzf" The purposeof this invention is to provide for pick-handles a protective socket,which shall be expansive and adjustable to the eye ofthe pick.

Figure l is a View ot' said socket in perspective. Fig. 2 is ahorizontalgtransverse section.

rlhis socket is of metal, preferably/kof malleable cast-iron, and may beof such length and breadth as may be preferred for various toolhandles.

The castings as they come from the tumbling-barrel are driven upon thehandles, a templet of proper size and form (corresponding to the eye ofthe pick) encircling the socket at the same. time to press it to theexact form and size of the eye ofthe tool, and to prevent overexpansion. Wedges, preferably of wood, are then driven into the endofthe handle, to iirmly secure it within the socket.

The interior of said socket may be of uniform diameter, or may tapereither way or both ways from tle center, to add to its iirmness when thehandle is wedged within it.

The exteriol` surface of the socket is preferably tapered from end toend, but may be formed with parallel sides, which, by wedging, can beforced to assume the taper of the pick-eye.

Referring to the drawings, a is the split or opening in said socket,which permits of its expansion. Said slit may terminate ina circularenlargement, as shown in-the drawing, or in any form preferred,calculated to prevent the continuation of the slit beyond the pointdesired, and at the same time allow sufcieut expansion.

These sockets can be finished at small eX- pense, no ling or grindingbeingreqnired to make them fit the pick-eye. nicety of t requisite maybe obtained Aby simply polishing the socket upon an emerybelt.

To attach for use, the pick or other tool is simply slid upon the handleand driven forcibly upon the socket.

The socket can be further expandedY at any future time by an additionalwedge.

I do not claim the attachment of picks to The greatest
